Minn. Stat. § 504B.145: RESTRICTION ON AUTOMATIC RENEWALS OF LEASES.

Notwithstanding the provisions of any residential lease, in order to enforce any automatic renewal clause of a lease of an original term of two months or more which states, in effect, that the term shall be deemed renewed for a specified additional period of time of two months or more unless the tenant gives notice to the landlord of an intention to quit the premises at the expiration of the term due to expire, the landlord must give notice to the tenant as provided in this section. The notice must be in writing and direct the tenant's attention to the automatic renewal provision of the lease. The notice must be served personally or mailed by certified mail at least 15 days, but not more than 30 days prior to the time that the tenant is required to furnish notice of an intention to quit.
